Urban thermal comfort: study case of the Floresta district of city of Belo Horizonte, MG

The study of urban thermal comfort enables the effects of human occupation on local climate to be evaluated. The urban environment may obstruct wind paths, causing changes in the temperature and phenomena such as heat island and thermal inversion. Such changes may lead to health problems, increase i...

The urban environment may obstruct wind paths, causing changes in the temperature and phenomena such as heat island and thermal inversion.

This paper aims to contribute to the development of an urban planning methodology concerned with both the environment and the human comfort, and also contribute to the preservation of thermal comfort conditions of the Floresta district in the city of Belo Horizonte, MG.

O estudo sobre o conforto térmico urbano permite avaliar o impacto da ocupação humana na alteração do clima local. A forma do meio urbano pode obstruir os canais de ventilação, ocasionando mudanças de temperatura e gerando fenômenos como ilha de calor e inversão térmica. Estas mudanças, por sua vez, causam problemas à saúde e aumento nos gastos de energia, bem como danos sociais e materiais devidos à mudança dos parâmetros climáticos locais. Neste estudo, procurou-se avançar em direção a uma metodologia de planejamento urbano comprometida com o meio ambiente e o bem-estar humano, contribuindo para a preservação das condições de conforto térmico do bairro Floresta de Belo Horizonte, MG. Características locais foram identificadas e registradas em sua distribuição espacial em mapas, definindo áreas homogêneas que serviram de base para formular uma hipótese de ventilação urbana local. Os dados de temperatura, umidade e ventos coletados em campo foram também registrados graficamente, após a aplicação de um índice de conforto térmico. Como resultado, gerou-se um mapa-síntese que define áreas que necessitam mudanças no seu desenvolvimento de forma a amenizar o impacto da ocupação sobre o clima local.
